Answers to the most popular questions
Custom systems aren't priced as a “fixed CRM rate” — they're scoped per project. Reference points on the Kyiv market in 2025–2026:
Exact pricing is fixed after a discovery phase (1–2 weeks). It's cheaper than paying Bitrix24 licences for 100+ employees over 3 years, and you own the system. Details are in the “Pricing” block above and on the development page.
Boxed CRMs are a great start for a small team. But Kyiv businesses usually hit the wall fast:
Run the numbers on current licence spend — custom often pays back in 1.5–2 years.
Over 15 years I've assembled a working stack of integrations for Ukrainian B2B:
If you need an integration with a non-standard service — we write an adapter. Examples in the portfolio.
Yes. The portfolio includes cases for manufacturing companies with material accounting, BOM (bill of materials), production planning, multi-warehouse stock management, order management and logistics. The Kyiv region is a complex one because of the high concentration of production sites (Boryspil, Brovary, Vasylkiv, Vyshgorod): you often need synchronisation between the Kyiv office and out-of-town warehouses, mobile interfaces for storekeepers and drivers, integration with 1C/BAS accounting and M.E.Doc.
A custom ERP doesn't try to be “everything for everyone” (like SAP at $500k) — it covers exactly your processes. Often this is 3–4 modules (warehouse, production, sales, finance) versus 30 in boxed solutions. A good fit if a boxed system doesn't cover your specifics and SAP/1C UPP is too expensive. We also recommend pairing it with business consulting at the start.
Multi-tenant is an architecture where one system serves many clients (tenants) with full data isolation. In plain English: one deployment, but each customer company sees only its data, settings, users and billing.
You need multi-tenant when you're building a SaaS product — selling the system on a subscription to other companies (rather than using it for your own ops). Examples from Kyiv: HR-tech for recruiting, edtech for learning platforms, fintech for accounting services, productivity tools for teams.
Multi-tenant architecture requires a careful approach from day one: row-level security in PostgreSQL, separate subdomains or custom domains, tariff plans with quotas, billing (often Stripe + LiqPay), self-service onboarding. This adds 3–6 weeks on top of the base scope — but without it SaaS simply doesn't work.
Roles and permissions are critical for any CRM/ERP/SaaS. In my systems, RBAC is built in layers:
This is especially important for Kyiv fintech, healthcare and legal companies — where direct regulatory requirements on access control apply.
My stack is stable — Next.js + Node.js + PostgreSQL + Redis + Docker. Why this one:
It's not a “trendy stack” — it's been validated on dozens of systems in production. Details on the development page.
Real timelines on the Kyiv market:
I work iteratively: discovery (1–2 weeks) → architecture design (2–3 weeks) → MVP (8–12 weeks) → 2-week sprints. The first useful result is in your hands within 2–3 months, not “in a year” as in classic waterfall projects. Critical for Kyiv startups dependent on an investment round or a sale to a customer.
Yes — data migration is a standard part of the project. I have ready pipelines for:
Migration isn't just “copy the tables”. It's field mapping, deduplication, format normalisation (phones, tax IDs, addresses), relationship verification (client → deals → payments). Usually 2–4 weeks for a CRM with 3+ years of history. We do a test migration on staging, you validate, then production goes in one window (typically Saturday night to Sunday so the working day isn't affected).
CRM/ERP/SaaS isn't “delivered and forgotten” — it's a living system that grows with the business. I offer three support formats:
All projects come with documentation in Notion/Confluence, monitoring (Sentry, Grafana), regular backups and a disaster recovery plan. If you want to hand over to another team — everything is ready for a painless hand-off. Get in touch via the contact form.
You own everything. Always. It's fixed in the contract: source code, design, DB schema, documentation — your intellectual property.
Hosting is your choice:
Backups — daily, with geo-distant storage. Disaster recovery — RTO 4 hours, RPO 1 hour as a standard.
Yes — take-over is a common scenario. The Kyiv market is full of contractors who started a project and didn't finish it, or tripled prices after the hand-off. My take-over process is standard:
Over 15 years I've seen cases where “rewrite from scratch” is cheaper than saving legacy. And cases where legacy is fine and brought to working state in 2 weeks. An honest assessment is part of my value.

Kyiv is Ukraine's largest B2B market. It hosts the headquarters of major banks (PrivatBank, Oschadbank, monobank, Sense Bank), IT giants (EPAM, GlobalLogic, SoftServe), retailers (Rozetka, EVA, Silpo), telecom operators (Kyivstar, Vodafone, lifecell), e-commerce leaders (Prom, Allo) and tens of thousands of mid-sized companies. They all hit the same wall: standard boxed systems (amoCRM, Bitrix24, even SAP) don't cover the specifics of their processes — they're either too limited, too expensive, or both.
I'm Alex Filiuk, Senior UI/UX designer and B2B systems architect with 15+ years of experience. I build custom CRM, ERP and SaaS products for Kyiv businesses that have outgrown boxed solutions or are building their own product from scratch. The portfolio includes 20+ systems running in production: cases for auto services, fintech, e-commerce, healthcare, production, manufacturing and distribution.
Boxed systems like amoCRM, Bitrix24, NetHunt, KeepinCRM are a great start for a 5–15 person team. But Kyiv businesses grow fast, and the typical pain points appear at 25–50 employees:
If at least 2 of these sound familiar — it's time to think about a custom system. Combined with business consulting and a UX audit of existing processes, this gives a clear understanding: what exactly to rewrite and what to leave on Bitrix24 for another six months.
I work with three main types of B2B systems, each with its own specifics:
CRM is the heart of the sales department. A custom CRM is worth building when:
My CRM functionality typically includes: leads and deals with a custom funnel, customer cards with full communication history, integration with Binotel/Phonet/Asterisk (popup on inbound, click-to-call, call recording), email via your SMTP or Gmail/Outlook API, commercial-proposal templates with auto-fill, e-signature (Diia, Vchasno), sales plans and progress tracking, manager dashboards. Integrated with email marketing and Google Ads — to see the full lead-to-revenue picture.
ERP is a comprehensive system covering everything: finance, warehouse, production, HR, logistics. A custom ERP makes sense when:
In ERP projects for Kyiv clients I've delivered: warehouse accounting across N warehouses (often Kyiv + the Kyiv region — Boryspil, Brovary, Vasylkiv), product catalogue management (10k–500k SKUs), BOM for production, order and logistics planning, integration with Nova Poshta API, Ukrposhta, Meest, finance with 1C/BAS and M.E.Doc sync, mobile interfaces for storekeepers and drivers (Progressive Web App or React Native).
SaaS is when you don't use the system “for yourself” — you sell it to other companies. It's the most complex and demanding type — you need multi-tenant architecture, tariff plans, billing, self-service onboarding, a public website, marketing integrations.
Kyiv is a powerhouse for SaaS startups: HR-tech, edtech, fintech, productivity, retail-tech. I help both launch from scratch and rewrite legacy monoliths into modern multi-tenant architectures with SSO, RBAC and full audit logs. Often you also need UI/UX work on the core product and conversion optimisation on the public site.
Over 15 years I've tried dozens of stacks. What stuck is a battle-tested set for B2B systems in the Ukrainian and global market:
This stack lets a team of 1–3 developers maintain a system serving 100k+ users. Critical for Ukrainian companies where the IT department is 5–10 people, not 100.
Unlike the western market, Ukrainian B2B requires deep integration with the local ecosystem. Without it, a CRM/ERP is only half a product. I have a ready stack of integrations that quickly adapts to your case:
If you need integration with a non-standard service (industry API, your supplier, specialised hardware) — we write an adapter from scratch. Details on the development page and in specific cases in the portfolio.
I don't believe in “six-month discoveries”. Real projects in Kyiv have economic logic — value should start showing as fast as possible:
Kyiv hosts a large number of companies with high security requirements: banks, MFIs, insurers, healthcare, legal, government contracts. For them, my systems are built with:
On the Kyiv B2B development market there are a few main options:
My positioning — Senior designer with deep architecture expertise + a network of trusted developers I've worked with for years. For Kyiv businesses with a $20–150k budget, this is often the optimal choice. Cheaper than EPAM, more reliable than “a guy from a freelance marketplace”.
My portfolio includes cases that illustrate the approach — custom B2B systems from scratch and legacy redesigns. The featured projects on this page include solutions for the auto-service market, auto-parts distribution, fintech and utility SaaS. For specifics, your case is best — write via the contact form, and at the discovery meeting I'll show 5–10 most relevant systems.
CRM/ERP/SaaS is part of an ecosystem. Often ordered together:
I work not only with Kyiv clients. CRM/ERP/SaaS projects run across Ukraine and abroad:
Full list — on the “Service Areas” page.
If you're hitting the limits of a boxed CRM, planning an ERP for a manufacturing site in the Kyiv region, or building your own SaaS — start with a free 60-minute discovery session. We'll discuss your business, current stack, pains, desired outcomes, approximate budget. After that you'll receive a detailed proposal with a fixed MVP-phase price and realistic timelines.
Fill in the contact form — within one business day I'll send a discovery slot. For Kyiv clients meetings happen on Zoom — I work fully remote. Ready to build a system that saves tens of thousands of dollars on licences and works exactly for your processes.
